•Corrosion of mild steel with aniline oligomer coating was investigated.•The change of the oxygen reduction kinetics to 2-electron path was observed.•Formed hydrogen peroxide oxidize initial Fe2+ corrosion products to Fe3+ which precipitate as Fe(OH)3.•During the corrosion process structure of the aniline oligomer remains practically unchanged.
Corrosion of the mild steel electrode with electrochemically formed aniline oligomers coating in 3% NaCl has been investigated by the means of electrochemical techniques and UV–vis spectroscopy. It has been shown that aniline oligomer coating, among barrier protection mechanism, change the mechanism of the oxygen reduction reaction from 4 to 2-electron path lowering the corrosion rate. The aniline oligomers structure has been slightly changed during the corrosion processes.
